   JS (uts-toc.js) checks the ACTUAL rendered background color of
   the page — not a guessed theme class name — and stamps
   data-uts-toc-mode="dark" / "light" on each TOC box. This works
   with any theme's toggle, whatever class/attribute it uses
   internally, and updates live the instant the user flips it.

   prefers-color-scheme below is only a same-paint-frame fallback
   for the brief moment before JS runs; the data-attribute (set

   Day / Night mode support (automatic)

   Base .uts-toc-container above already defaults --uts-toc-text

   mode below only overrides the variable; it never depends on
   JS having tagged the box first.

   JS (uts-toc.js) additionally checks the ACTUAL rendered

   would flash dark for a moment on every load/refresh before JS
   corrected it. The JS below (uts-toc.js) checks the page's real
